Just plugged the POIs into the Magellan Maestro 4350 (a good device, and a GREAT value if you can pick one up on sale for $150 … they once were $499):

– 7303 miles. Although that adds some waypoints that we may not go to, and factors in street directions that we won’t necessarily use (i.e., Grandpa’s to Uncle Jim’s house).
– 134 hours of driving time. I don’t know if we have enough movies.
I also figure that’s roughly 17 fill-ups of the rental minivan. Should be interesting watching the fuel prices rise along this trip; I opted to “buy a full tank” from Hertz, saving a few pennies with the $2.81/gallon rate they offered. Extra donuts in Portland for all.
